1. An apparatus for measuring environmental parameters, comprising:
- an optical fiber sensor configured to be disposed along a path in an environment to be measured, the path of the optical fiber sensor defining a longitudinal axis; and
at least one section of the optical fiber sensor disposed in a housing configured to maintain an entire length of the at least one section at an at least substantially homogeneous environmental parameter, at least part of the at least one section extending in a direction having a radial component relative to the longitudinal axis.

Abstract
An apparatus for measuring environmental parameters includes: an optical fiber sensor configured to be disposed along a path in an environment to be measured, the path of the optical fiber sensor defining a longitudinal axis; and at least one section of the optical fiber sensor configured so that an entire length of the at least one section is exposed to an at least substantially homogeneous environmental parameter, at least part of the at least one section extending in a direction having a radial component relative to the longitudinal axis.

13. A method of monitoring an environmental parameter measurement apparatus, comprising:
-
disposing an optical fiber sensor along a path in an environment to be measured, the path of the optical fiber sensor defining a longitudinal axis, the optical fiber sensor including at least one section configured so that an entire length of the at least one section is exposed to an at least substantially homogeneous environmental parameter, and at least part of the at least one section extending in a direction having a radial component relative to the longitudinal axis; transmitting an electromagnetic measurement signal into the optical fiber sensor and receiving return signals from a plurality of measurement locations disposed in the optical fiber sensor and the at least one section; estimating the environmental parameter at each of the plurality of locations and generating a profile, the profile including at least one profile portion corresponding to the at least one section; and analyzing the at least one profile portion to monitor the performance of the optical fiber sensor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
